PCM 80 User Guide
In the Resonant Chord algorithms: Res1>Plate and Res2>Plate, this row
contains high cut filter and resonance controls for each voice, as well as master
high cut and resonance controls for all voices.
Mstr Res,Mstr HC
Position 0 of the Resonance row contains two master parameters for the six
resonator voices: Mstr Res and Mstr HC. (Press Load/✱ to toggle between
them.) Mstr Res is a master resonance control for all of the resonator voices.
It allows the resonance settings for all voices to be scaled over a range of 0-
100%. Use care when adjusting this value. The resonators will put out high
levels if the input source has any components that are close in pitch to the
resonator tunings.
The Mstr HC control allows the high cut filter settings for all voices to be scaled
over a range of 0-100%.
V1Res,V1 HiCut-V6 Res,V6 HiCut
TheV1-V6 Res controls set the amount and polarity of feedback for each voice.
The HiCut controls set the high frequency cutoff frequency of the 6dB per
octave low pass filter for each voice.
The Reverb Deisgn row, available in every algorithm, contains parameters that
affect the structural aspects of the reverb effect.
Size
Size sets the rate of build-up of diffusion after the initial period (which is
controlled by Diffusion). The Size control changes a reverb sound from very
large to very small. Generally, you should set this control to approximate the size
of the acoustic space you are trying to create, before adjusting anything else.
The size in meters is roughly equal to the longest dimension of the space. Audio
is temporarily muted when Size is changed.
Duration
In the Inverse algorithm, Duration determines the length of time, in milliseconds,
which passes before the cutoff in Inverse effects.
Attack
Attack is provided in the Plate algorithm to set the sharpness of the initial
response to an input signal. High settings cause an explosive sound, while low
settings cause the sound to build up more slowly with time. Attack only affects
the level of sound within the first 50 milliseconds.
Diffusion
A Diffusion control is provided in all algorithms. It controls the degree to which
initial echo density increases over time. High settings of Diffusion result in initial
build-up of echo density, and low settings cause low initial build-up. Echo density
is also affected by Size; smaller spaces will sound denser. To enhance
percussion, use high settings of Diffusion. For clearer and more natural vocals,
mixes, and piano music, use low or moderate settings of Diffusion.
